Resumo: | The objective of this research was to evaluate the best type and adequate content of adhesive in low density particleboards produced with corn cob, in addition to the chemical analysis of the particles. The adhesives used were urea-formaldehyde (UF) and phenol-formaldehyde (PF) distributed in three levels (6, 9 and 12%) on the dry mass of the particles and the nominal density was 0.60 g.cm-3. Regarding the water absorption and swelling properties, no significant differences were found between treatments. The mean value calculated for the IE 24 h was 37.07%, being above the minimum limit stipulated by the standard. The modulus of rupture (MOR) and modulus of elasticity (MOE), were influenced by the tested factors. All particleboards met the requirements of the standard norm. For internal adhesion there was a significant effect only for the type of adhesive factor, with the particleboards produced with PF showing the highest means. For the compression property there was no effect of the factors tested. In general, the dimensional stability of the particleboards was below the minimum required by the standard, but the mechanical properties met all requirements. |

Los adhesivos utilizados fueron urea-formaldehído (UF) y fenol-formaldehído (FF) distribuidos en tres niveles (6, 9 y 12%) sobre la masa seca de las partículas y la densidad nominal fue de 0,60 g.cm-3. En cuanto a las propiedades de absorción e hinchamiento de agua, no se encontraron diferencias significativas entre tratamientos. El valor medio calculado para IE 24 h fue del 37,07%, por encima del límite mínimo estipulado por la norma. El módulo de ruptura (MOR) y el módulo de elasticidad (MOE) fueron influenciados por los factores probados. Todos los paneles de aglomerado cumplieron los requisitos de la norma estándar. Para la adherencia interna hubo un efecto significativo solo por el tipo de factor adhesivo, y los paneles producidos con FF mostraron los promedios más altos. Para la propiedad de compresión no hubo efecto de los factores probados. En general, la estabilidad dimensional de los paneles estuvo por debajo del mínimo requerido por la norma, pero las propiedades mecánicas cumplieron con todos los requisitos.O objetivo desta pesquisa foi avaliar o melhor tipo e teor adequado de adesivo em painéis aglomerados de baixa densidade produzidos com sabugo de milho, além da análise química das partículas. Os adesivos utilizados foram uréia-formaldeído (UF) e fenol-formaldeído (FF) distribuídos em três teores (6, 9 e 12%) sobre a massa seca das partículas e a densidade nominal foi 0,60 g.cm-3. Em relação às propriedades de absorção de água e inchamento, não foram constatadas diferenças significativas entre os tratamentos. O valor médio calculado para o IE 24 h foi 37,07%, acima do limite mínimo estipulado pela norma. O módulo de ruptura (MOR) e o módulo de elasticidade (MOE), foram influenciados pelos fatores testados. Todos os painéis aglomerados atenderam aos requisitos da norma padrão. Para a adesão interna houve efeito significativo apenas para o fator tipo de adesivo, sendo que os painéis produzidos com FF evidenciaram as maiores médias. Para a propriedade de compressão não houve efeito dos fatores testados. De forma geral, a estabilidade dimensional dos painéis ficou abaixo do mínimo requerido pela norma, mas as propriedades mecânicas atenderam a todos os requisitos.Research, Society and Development2021-09-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1982810.33448/rsd-v10i11.19828Research, Society and Development; Vol. 10 No. 11; e541101119828Research, Society and Development; Vol. 10 Núm. 11; e541101119828Research, Society and Development; v. 10 n. 11; e5411011198282525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/19828/17822Copyright (c) 2021 Marina Resende Ribeiro de Oliveira; Flávia Maria Silva Brito; Luciana Silva Villela; Lourival Marin Mendes; José Benedito Guimarães Juniorhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessOliveira, Marina Resende Ribeiro deBrito, Flávia Maria SilvaVillela, Luciana SilvaMendes, Lourival MarinGuimarães Junior, José Benedito 2021-10-23T19:01:11Zoai:ojs.pkp.sfu.ca:article/19828Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:39:38.735532Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
